MT6329 datasheet pdf


The MT6329 is a power management system chip optimized for 2G/3G handsets and smart phones, especially those based on the MediaTek MT6575 system solution. MT6329 contains 15 buck converters and 21 LDOs, which are optimized for specific 2G/3G/smart phone subsystems.

The device provides dual-channel, 0.7W into 8Ω, high efficiency Class AB/D audio amplifiers and flexibility for various applications of backlight LED drivers. It supports up to 6 WLEDs in parallel or alternative series 10WLED configurations. Flexible control keeps high power efficiency while supporting multiple drivers.

Sophisticated controls are available for powerup, battery charging and the RTC alarm. The PMIC is optimized for maximum battery life. The selectable 1-step or 2-step RTC LDO design makes MT6329 suitable for different RTC modules in BB chips. It allows the RTC circuit to stay alive without a battery for several hours. The battery charger in device supports lithium- ion (Li-ion) battery and provides precharge indication. The charger input voltage can be up to 10V and allows USB charging, too.

Featues :

1. Handles all 2G/3G/smart phone baseband power management

2. Input range: 3.4 ~ 4.3V

3. Charger input of up to 10V

4. 5 buck converters and 21 LDOs optimized for specific 2G/3G/smart phone subsystems

5. Dual-channel, 3.7V 0.7W into 8Ω Class AB/D audio amplifiers
